I saw this on aliExpress, a TPA3255 with feedback from 3eAudio.

You could, but that doesn't have the PFFB (more distortion, load-sensitive frequency response), quality coils (distortion again), balanced inputs (freedom from ground loop issues) or the heatsinking options (sustained power output). The 3E is more capable than the A07 but at a price. Whether it's worth it depends on what you need.A good board, but you could buy a fully built aiyima A07 for less.
Very interesting, is it easy to get a case and assemble this?.I saw this on aliExpress, a TPA3255 with feedback from 3eAudio.

Yes it is very easy. I have made several. If you want help, go to the diyAudio forum in the class D amp section.Very interesting, is it easy to get a case and assemble this?.
Similar performance to the Aiyima A07 at almost double the price? I guess if you really like the meter or the separate volume controls...This reviewer likes the AOSHIDA A7 amp:

REVIEW/MEASUREMENTS: AOSHIDA A7 Class D TI TPA3255 amplifier. Good sound. Good power. Economical.

The Aoshida A7 has XLR inputs, might be a preference to some, I guess.Similar performance to the Aiyima A07 at almost double the price? I guess if you really like the meter or the separate volume controls...

Myself included. Pity the measurements didn't investigate them more - CMRR, whether there's a 'Pin 1 Problem' etc. I'd probably look at sticking InGenius modules in the A07 though.The Aoshida A7 has XLR inputs, might be a preference to some, I guess.
